  1. Both of these globulars are in the constellation Tucana but are in two different galaxy. 47 Tuc is in our own Milky Way and NGC121 is in the Small Magellenic Cloud. NGC121 may even be larger than 47 Tuc. http://www.pbase.com/grahammeyer/image/168197638/original Telescope: William Optics FLT132 Guide Scope: QHY OAG Camera: QHY9 Mono @ -20c Filter Wheel: QHY 7 position Ultra Slim Filters: QHY 36mm unmounted L R G B HA OIII SII Guide Camera: QHY5L-II Mount: AZ-EQ6 Mount Control: EQASCOM Focusing: SharpSky Pro and Sequence Generator Pro 3 (automated) Bahtinov Mask: No Capture Software: Sequence Generator Pro 3 Guiding Software: PHD2 Calibration and Stacking Software: PixInsight Processing Software: PixInsight Number and Type of Data Frames: L= 19X300 sec, L =7X120 sec, L= 14x30 sec, R= 10x180 sec, G= 10x180 sec, B= 10x180 sec Ha= x , SII= x , OIII= x .

    NGC 104 and 121

    I had the chance to finish my image of NGC104 and the field of view also allows NGC121 to sneak into the frame. NGC121 is located in the Small Magellanic Cloud, so two globulars in two galaxies. I had to murder the data a bit as for some reason my flat frames have started over correcting so I processed it to hide the dust bunnies. Happy enough with the result. You can use the size buttons on the bottom of the page if you wish a different size. http://www.pbase.com...197638/original For interest and comparison, here are some specs for both objects, courtesy of Wkipedia (accuracy not verified) NGC121 NGC104 Constellation Tucana Tucana Distance 199 Kly 13,000 +/- 1,100 ly Magnitude 11.24 4.09 Size 175ly 60ly Age 10 billion years Not given There are differing estimates for both of these, NGC 121 seems to have more consistent data, NGC104 seems to vary a bit in distances and a lot in size, from 60 to 150 ly. Thanks for looking.
  3. Hi. In reference to this rule, does this exclude submitting a colour version if I have already submitted a black and white image of the same object? Thanks.

    Thanks for the comments and the likes, I'm glad you enjoyed the view.

    M17 Take 2

    I felt that my other version was not the best and after getting my Photometric Colour Calibration working I have decided to do a reprocess. http://www.pbase.com/grahammeyer/image/167991880/original.jpg Image details Telescope: William Optics FLT132 Guide Scope: QHY OAG Camera: QHY9 Mono @ -20c Filter Wheel: QHY 7 position Ultra Slim Filters: QHY 36mm unmounted L R G B Guide Camera: QHY5L-II Mount: AZ-EQ6 Mount Control: EQASCOM Focusing: SharpSky Pro and Sequence Generator Pro 3 (automated) Bahtinov Mask: Yes (initial focus) Capture Software: Sequence Generator Pro 3 Guiding Software: PHD2 Calibration and Stacking Software: PixInsight Processing Software: PixInsight Number and Type of Data Frames: L=30X10 min, R=6x7 min, G=6x7 min, B=6x7 min Ha= x , SII= x , OIII= x .

    M17

    Hello! Wow, there are really some more great images here, keep up the good work everyone. This one has been another struggle for me, I am not getting the best out of my scope and kit, with silly little issues all the time. Might be time to re-assess my options. Anyway, it has taken 12 months of data collection to get this far on this one and where I am in Australia the weather has been rubbish for winter and data collection has been hit and miss. So here it is, M17 in LRGB. http://www.pbase.com/grahammeyer/image/167991880/original.jpg Apart from stretching, colour calibration, enhancing and a couple of other steps, there is no image sharpening, it is straight from the scope. If anyone has any thoughts re sharpening, let me know. Thanks for looking.

    Sequence Generator Pro 3

    Not wanting to hijack the thread although a quick answer here is to delete your alignment model and set EQMod to Dialog based and let SGP plate solve its way to the target.
  8. This is open cluster Pismis 4 in the Vela constellation and backed by part of the Vela supernova remnant. Some information regarding Paris Pismis and her catalogue can be found on this link. http://sandandstars.co.za/2018/01/25/paris-pismis-and-her-catalogue-of-open-clusters/ Telescope: William Optics FLT132 Guide Scope: QHY OAG Camera: QHY9 Mono @ -20c Filter Wheel: QHY 7 position Ultra Slim Filters: QHY 36mm unmounted L R G B Guide Camera: QHY5L-II Mount: AZ-EQ6 Mount Control: EQASCOM Focusing: SharpSky Pro and Sequence Generator Pro 3 (automated) Capture Software: Sequence Generator Pro 3 Guiding Software: PHD2 Calibration and Stacking Software: PixInsight Processing Software: PixInsight Number and Type of Data Frames: L= 18X10 min, R= 6x7 min, G= 6x7 min, B= 6x7 min Binning: 1x1 Total Image Time: 306 minutes Location: Lockleys Observatory B, Tanunda, Sth Australia Light Box by Exfso

    That's a cracker!
  10. Very lovely work. I like "Wall-E", very clever from the kids and nice, neat set up!

    rgb images how do you know

    Well, here is a very quick LRGB combination in PixInsight. Everything is as it should be as per the colours. There is a lot to like about your data, I think it only needs more exposure time and more frames per channel. I use SGP as well so it has its own naming convention which seems to be working as long as you fill out the sequence correctly. Good luck, waiting to see more from you!

    rgb images how do you know

    What software are you using to capture and process?
  13. Hi, Does anyone know how to search by co-ordinates in Starry Night 7 Pro Plus. I'm looking for a couple of objects that do not seem to be in its data base. I've tried the Advanced Search function and that did not seem to do it either? LOL! Am I missing something obvious? Thanks.

    rgb images how do you know

    Hi. The file, if saved in a .FIT or .FITS format should contain information relating to the image like time, location, camera temperature as well as the filter used. It is called the FITS Header and many astro processing programs and the like should allow you to read that info. It also pays to develop a naming convention to use for your files to help you quickly identify each image. Most astro capture programs may already have a naming convention as part of the capture process. Also, have you tested the filter wheel to ensure that it is working when you ask it to change filter slots? Cheers.

    Very nice, lovely processing!
